PULL-SWITCH SOCKET FOR ELECTRIC LAMPS.

Specification of Letters Patent.

Application led October f5, 1913. Serial No. 793,532.

To all whom t may concern.'

Be it known that I, REUBEN B. BENJA- MIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful 4As sockets of this class are usually constructed, if a shade is used, the operating chain or cord extends over the edge of the shade and hangs down from this point to where it can be reached by a person desiring to manipulate the switch. When the chain or cord is pulled the fixture is jarred or caused to vibrate to such an extent as to endanger the filament of the lamp, especially if the latter be a tungsten or other metallic filament lamp, which, as is well known, are not adapted to rough usage. This jarring is due to the fact that the pull occurs at a point considerably removed from the axis of the socket and to the engagement of the chain or cord with the edge of the shade.

It is the principal object of my invention A to remedy the above defects and to provide a pull switch socket in which the possibility of the fixture being jarred or caused to vibrate is reduced toa minimum.

It is a further object of my invention to .provide a convenient and simple construction of pull switch socket in which the switch operating member is disposed between the lamp and any shade which may extend from the socket.

In the accompanying drawing and the following description I have disclosed one preferred embodiment of my invention, but I wish ity understood that changes may be made in the form, construction, and arrangelnent of the parts without exceeding the scope of the appended claims.

In the drawings: Figure 1 is a side elevation of a pull switch socket constructed in accordance with my invention, a part of the.

same beingbroken away to disclose the connection and arrangement of the switch operating member; and Fig. 2 is a front view of the same.

'Ihe socket comprises a tubular casing shell 3 formed of sheet metal or other suitable material, and lined with fiber or other insulating material. In the upper part of the casing 3 is arranged a switch mechanism ofany suitable type which is adapted to be operated by means of a cord or chain. The casing 3 is also adapted to contain the usual screw-threaded lamp engaging contact shell, and is provided with an annular .bead 4 which serves as a support for the holder 5 of a shade 6. A cap 7 is provided to fit over the top of the casing 3 and is held in place by the spring retaininrm members 8, which are formed in the casi lg The cap 7 is provided with a boss 9 to which is secured a bushing 10, screw-threaded on the interior for engaging the conduit or feed wires. The shell 3 has an enlarged portion to contain the insulating. base for the contacts, said enlarged portion forming, on the casing 3, a shoulder 11. In the lower face of the shoulder 11 is a downwardly directed aperture 12. In this aperture is secured an elongated hollow rivet 13 through which the switch operating member is adapted to pass. The switch operating member is a chain 14C composed of thin,^f1at links. If so desired, it may have an extension 15 of any ornamental form.

It will be noted that, by virtue of the construction and arrangement of my socket shell and chain, the chain 14. lies close to the side. of the casing 3, so that, being of attenuated cross section, it can pass, without any appreciable change in its direction, through the space existing between'the shade 6 and the lamp. In pull switch sockets as usually constructed, the operating member, usually a ball chain, emerges from the casing above the shade and hangs down the outside and over the edge thereof. Such vsockets are open to the important objection that when the switch is operated consider- Patented May a3, i916.-

able vibration of the lamp is caused, and the what rI. lcla'ir'rr'as new and desire to secure by Letters Patent isl. A lamp socket including a casing havlng the lower portion thereof reduced to form a shoulder and having a guide opening formed in said shoulder, a pull switch contained in said casing, and an operating kmein-ber for said switch passing through said guide opening, for the purposes set forth.

2. In combination, a lamp socket including a casing having the' lower portion thereof reduced to form a shoulder and having a guide opening formed 1n sa1d shoulder, a

lamp contained in said socket, a shade associatcd with said socket, a pull switch contained in said socket, and an operating member for said switch passing through said guide opening, said operating member having a portion thereof formed of attenuated cross section and passing through the space between said shade and said lamp.

8. In combination, a lamp socket, a shade holder lcarried thereby having an opening therein affording a passage from the outside of the socket to the space between the shade and lamp, a switch associated with said socket, and a switch operating member connected with said switch and passing through said opening to a position in which it will lie between the lamp and shade.

4:. In combination, a lamp socket, a shade carried thereby, a switch associated with said socket, a casing surrounding said socket and switch and having an opening in the side thereof, andy switch operating means connected with said switch and passing through said opening and through the upper part of said shade to a position between said shade and the lamp.

5. In combination, a lamp socket, a shade holder carried thereby having an opening therein, a switch associated with said socket, a casing surrounding said switch and socket having an opening in its side, and switch operating means connected with said switch and passing through both of said openings to a position in which it will lie between the lamp and shade.

6. A lamp socket including a casing hav- 4 ing the lower portion thereof reduced to form a shoulder and having an opening formed nesses.
